well, Plutom, i've tried everything i can think of to try to resolve the battle of the closing program but with me as the victor of said battle, and i'm at a loss... sigh...

i typically only render a nude figure and go from there, though at times, i might add a few lightweight in size props.  P7 closes on me under the most simplistic circumstances - ie, nude V4 under a spot & 2 omni lights without shaders being used on the V4 texture and without any nodes attached to lights, etc..  it also collapses on me if the texture does have shaders being used and a bit more complex lighting.  i'm not raytracing or anything either.  all my drivers are up to date and my prefs are set properly according to the manual and what's appropo for my system.

i've run countless searches here in forum to try to see if i can turn up anything to help, but so far nothing has worked.  and P7 closing on me is so inexplicably random, too, that i can't discern any kind of patterning in what might be prompting it to shut down on me.  for example, it might close during a render, but then i reopen the saved PZ3 file, and render things and everything works just fine.

it's a mystery... heh...
